I have taken a NRA course and my feeling was that the instructor probably picked up a firearm for the first time 3 weeks before teaching this class. I have no idea if that is correct but it was my distinct impression. This is not to say that NRA courses are not good but the experience of the instructor is very important to me.
I would look into some level 2,3,4 pistol courses at a tactical school if it were me.
